I failed emission test with code p0420 po300 andd
P0101 isit the catalytic converter or oxgen sensor? How much will I have to pay to get it repaired at a muffler shop. Oh no misfire

You need a cat. Get a good quality cat not a cheap one. After it is repaired, it needs to be driven to see if the missfire goes away. The 101 is a mass air flow code but doesn not mean it needs to be replaced. Have it checked first

Which cat would this be referring to? There's one connected to the exhaust manifold itself on the 2.4l and then there is either another one before the muffler or a resonator. Only saw sensors near the first one.
